SPECIFICATION forming part of Letters Patent No. 558,623, dated April21, 1896. Application filed October l2, 1895. Serial No. 565,500. (Nomodel.)

To all whom it may con/cera.- i

Bc it known that IVARREN II. TAYLOR, a

citizen of the United States, residing at Stainford, in the county ofFairfield and State of Connecticut, have invented certain new and usefulImprovements in Padlocks, of which the following is a specification.

My present invention relates to an improvement in padlocks, and has forits especial object an improved means for securely locking both ends ofthe shackle, and particularly in that class of padlocks where theunlocking motion of the shackle is automatic-that is, when the key hasperformed its unlocking function the shackle will be automaticallyprojected outward and when returned to place will be automaticallylocked; and my invention consists in applying to the above class ofpadlocks a rotary latch which engages both ends of the shackle and whichwhen the shac kle is projected its end will hold the latch in unlockedposition; but when the shackle is returned to the casing it will beautomatically locked at both its ends.

In order that my invention may bc fully understood, I will proceed todescribe t-he same, with reference to the accompanying drawings, inwhich- Figure 1 is a front view of one form of padlock. Fig. 2 is avertical section thereof. Figs. 3 and 4 are detail sections taken on thelines 3 3 and 4 4, respectively. Fig. 5 is a bottom view of the padlockshown in Fig. l. Figs. 6 and 7 are respectively afront and edge view ofanother form of padlock. Fig. S is a vertical section of the same.vFigs. 9

" and 10 are detail sections taken on the lines 9 9 and 10 10, Fig. 8;Vand Fig. 11 are .detail views of the key-springs employed in this formof lock. Fig. 12 is a View of the key employed in the form shown inFigs. 6 to S.

In the said drawings, and referring more particularly to Figs. l. to 5,1 represents the casing, formed in two parts, as shown, and sccuredtogether by the pins or rivets 2, and 3 representsthe shackle, which isof the usual form. The shackle is secured in the casin g by means of thelatch 4, which is carried by the barrel 5 of the lock 6. In thisform Iemploy the Yale pin locking mechanism. The

latch is Afitted on the pivot-pin 7 of the barrel, and itis formed withthe slot G, through which pro jects a pin 8, also carried by the barrel5.

9 represents a spring having one end fastened to the latch and the otherend bearing against the casing. The operation will be readily seen. Thekey is inserted in the barrel-opening 10 and the pins adjusted by it sothat the barrel can rotate. This rotation turns the latch and disengagesit from the grooves 11, formed in each end of the shackle. This willpermit the spring 12 to force the shackle upward, and as it reaches itshighest position a turn is given the shackle. This is accomplishedbyallowing the cam 13, carried by the shackle, to enter the groove 14 inthe lock-case. Then the shackle is in its unlocked position, the latchis prevented by the portion 15 of the shackle from returning to itsnormal position, and it is only when the grooves 11 are in the positionshown in Fig. 2 that the spring will force it to its normal position.

It will be understood that the slot in the latch is long enough topermit the barrel to be turned, so that the key can be removed.

In the forni shown in Figs. 6 to 11 the same idea is employed; but thekey 16 turns the latch. In this form 17 represents the barrel, which issu pported within the case by the staypieces 18, and 19 represents thekey-springs. The operation of this form is practically the same as inthe other. The key 1G is inserted in the barrel and its end engages inan opening 20 in the latch and the turning of the key will disengage itfrom the grooves in the shackle, when the spring 2l will force theshackle upward. The latch is prevented from returning to normal positionby the face 22 thereof coming into engagement with the portion 15 of theshackle. NVhen the grooves are in the proper position, the spring 23will force the latch into them and thus lock the shackle.

Having thus described my invention, the following is what I claim as newtherein and desire to secure by Letters Patent:

1. In a padlock, the com binaiion of the casing and shackle, a lockingmechanism and rotating latch carried thereby and adapted to engage bothends of the shackle, suitable IOO means for automatically forcing theshackle ont of the casing and turning it, so that the latch Will bearagainst one end of the shackle and be held in unlocked position,substantially as shown and described.

2. In a padlock, the combination of the casing, and the shackle, thelock mechanism, a latch pivotally carried by said lock mechanism, andadapted to engage both ends of the shackle, and a loose connectionbetween the latch and lock mechanism, substantially as shown anddescribed and for the purpose set forth.

3. In a padlock, the combination of the casing and the shackle, a latchinovably snpported therein and adapted to engage both ends of theshackle, a spring for holding it in engagement With the shackle ends, asnit-able opening formed in the latch ntoWhich the means for disengagingthe latch from the shackle ends fits, substantially as shown and zodescribed.
